I hope so.

In practice measurements are usually a fraction of the stated maximum.
On radio networks the fraction is larger, but all networks experience
variable amounts of congestion. Both end users and sysadmins use
various tools to measure these statistics. An example would be a
broadband user visiting a web page to measure their bandwidths, or a
sysadmin periodically measuring the total time for a file transfer.

Not all of it, but many Unix-derived APIs provide system calls and
tools to measure 3, 4, 5, and 6.
7 and 8 are measured by consumers and influence decisions in selecting
equipment and service providers. I would love to have those decisions
automated, but law enforcement agencies, for example, might be opposed
to enhancing privacy, and corporations are likely to be opposed to
providing more easily available price information unless the are sure
that they offer the best prices. I hope that the W3C maintains their
longstanding efforts towards greater privacy and effective consumer
choice.
The expectation of privacy is proportional to cost, too, because of
the principle of reciprocity -- if you don't have to worry about
privacy violations, then the people you communicate with don't have to
worry about them either.
